By definition, tracing is outlining parts of the body (arms, head, legs, etc.) with glowsticks. This is the most expressive and visually appealing aspect of glowsticking. Traces can be done all over the body, in both symmetrical and asymmetrical forms.This type of trace is localized around the abdominal (stomach) region. The trace involves moving the glowsticks so that you create the illusion of a circle on your stomach. The circle can be going either clockwise or counter clockwise (first person view). Watch this how to video and you will be performing the stomach trace with glowsticks in no time.
